similar to: compressed audio tutorial - "major" update

Hello. The page http://www.vorbis.com/faq.psp (last faq) and http://cs.leander.isd.tenet.edu/~mitchell/vorbis_intro.html both state that it's possible to lower the bitrate of an existant ogg enc file without reencoding. Where does this feature exists? oggenc only likes wav files as input, how can I feed it an .ogg file and get a lower bitrate in a new one? -- Grzegorz Adam Hankiewicz

I've updated the "Introduction to compressed audio with Vorbis" tutorial based on the many good corrections and suggestions I got here. Changes were: fixed range of 16bit samples (-32768 to 32767 rather than 0 to 65535) added sentence on why 44.1KHz was chosen for CDs added Sony's name as developer of CD format wrong word ("Which" ->

On <http://cs.leander.isd.tenet.edu/~mitchell/vorbis_intro.html>: "Each snapshot has a 16-bit number for the "loudness" of the sound, meaning that the scale is fairly fine-grained - it ranges from -32,768 (complete silence during that snapshot) to 32,767 (the loudest volume measurable)." That's not correct. A single sample is not meaningful by itself; each sample

Hey all. Two topics: First, I teach Computer Science at the high school level at a largish school near Austin, Texas. For the past several years there's been a "jukebox" in my room where students could vote for albums to hear during programming lab time, and random tracks off the winning albums play over the speakers in the classroom. This past week I changed the

Many of you have read and my "introduction to compressed audio with Vorbis" and given me excellent feedback. But with 1.0 about to hit the streets, I figured I'd freshen it up a bit. [ http://grahammitchell.net/writings/vorbis_intro.html ] In particular, it contains two paragraphs discussing the relative quality of Vorbis vs mp3 at a certain target bitrate. These figures seem

Hello everyone, I would like to bring to your attention the new website that I have been working on. It is a portal for articles, links, and support for everything related to Ogg Vorbis. It just started and hopefully will be evolving rapidly. http://www.ogghelp.com I have modeled it after the group of successful Help pages such as http://VCDHelp.com and DVDHelp.com. I've been

I remember hearing that there was a sound quality issue which boosted high frequencies by 1 or 2dB in Vorbis files at less than q6 or so. Does anyone know if this still the case? -- Graham Mitchell - computer science teacher, Leander High School "I come into His presence simply. No

It's mostly waiting on an updated Win32 SDK, if I understand things correctly. 1.1 is not anytime soon, and is the "AAC-killer" version, I think. -- Graham Mitchell - computer science teacher, Leander High School

For the two or three of you who are subscribed to the mailing list that *haven't* heard already... from the blurb on Slashdot: "Xiph.org has made a beta release of firmware with Ogg Vorbis support for the Neuros portable music player. You can grab the firmware from the Neurosetta site. Note that this beta release only plays Vorbis files, and may skip on very high quality files, like

You know, we really need a streaming FAQ. There seem to be LOTS of undocumented command-line switches for oggenc that help in limiting bitrates that folks don't know about. The recent thread with Derek at CD Baby brought out a lot of good info that I didn't know, and I consider myself fairly plugged-in. It would be helpful to have something like: Q: How do I limit the bitrate to

This is off-topic, mostly, but I figure you guys will have some knowledge in this sound-quality-related area. I'm sitting here looking at the most recent "Musician's Friend" at headphones and thinking about getting a pair. They've got products from AKG, Fostex, Audio Technica, Nady, Sennheiser, and Sony, at price points ranging from $16 to $130 (list prices $20 to

Okay, my responsibilities at school have recently eased up a bit, and I might have some actual free time over the coming months. So I'd like to volunteer my services to write some needed documentation, tutorials, FAQs, etc. I am "fluent" in C and C++ and am not bad at Perl. I have been told I'm good at explaining things. I am anal-retentive about grammar, syntax, and
